定時后自動推進Powerpoint幻燈片放映動畫

Question

我有一個使用C＃訪問的幻燈片幻燈片。 它會打開並顯示在屏幕上，我可以手動瀏覽它，但是在“動畫”選項卡中已經有計時。 我如何才能開始播放並根據PowerPoint中“動畫”中的設置運行？

Microsoft.Office.Interop.PowerPoint.Application app = null;
Microsoft.Office.Interop.PowerPoint.Presentation pres = null;
app = new Microsoft.Office.Interop.PowerPoint.Application();
app.SlideShowNextSlide += new Microsoft.Office.Interop.PowerPoint.EApplication_SlideShowNextSlideEventHandler(app_SlideShowNextSlide);
pres = app.Presentations.Open(filename,
                Microsoft.Office.Core.MsoTriState.msoTrue, Microsoft.Office.Core.MsoTriState.msoTrue, Microsoft.Office.Core.MsoTriState.msoFalse);
//I was hoping this line would just run my show with the timings but it does not.
pres.SlideShowSettings.Run();
pres.SlideShowWindow.View.First();

為了手動前進，我一直在做

pres.SlideShowWindow.View.Next();

Answer 1

事實證明，我只需要多一行就可以激活動畫定時。

pres.SlideShowSettings.ShowWithAnimation = Microsoft.Office.Core.MsoTriState.msoTrue; 

完整代碼

Microsoft.Office.Interop.PowerPoint.Application app = null;
Microsoft.Office.Interop.PowerPoint.Presentation pres = null;
app = new Microsoft.Office.Interop.PowerPoint.Application();
app.SlideShowNextSlide += new Microsoft.Office.Interop.PowerPoint.EApplication_SlideShowNextSlideEventHandler(app_SlideShowNextSlide);
pres = app.Presentations.Open(filename,
            Microsoft.Office.Core.MsoTriState.msoTrue, Microsoft.Office.Core.MsoTriState.msoTrue, Microsoft.Office.Core.MsoTriState.msoFalse);
pres.SlideShowSettings.ShowWithAnimation = Microsoft.Office.Core.MsoTriState.msoTrue;
pres.SlideShowSettings.Run();
pres.SlideShowWindow.View.First();
